WILLIAM P. NASH, OF ROCKY, OKLAHOMA.

WASHING-IEACHINE.

Specification of Letters Patent. Patented Aug. 24, 1909.

Application filed June 2, 1909. Serial No. 499,768.

To all whom it may concern:

Be it known that 1, WILLIAM P. NASH, a citizen of the United States, residing at Rocky, in the county of Washita and State of Oklahoma, have invented certain new and useful Improvements in lVashingli lachines, of which the following is a specification.

This invention relates to washing machines and more particularly to that class of washing machines commonly known as clothes pounders.

The object of the invention is to provide a comparatively simple and thoroughly efficient device of the character described having means for forcing a current of air through the clothes during the washing operation.

A further object is to provide a clothes pounder including a cone shaped body portion having a plurality of tubular members or cells secured to the interior walls thereof and connected through the medium of suitable conductors with an air chamber, there being a piston mounted for reciprocation within said chamber for forcing a current of air through the several cells and through the clothes in the containing tub or vessel.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability, and efliciency, as well as to reduce the cost of manufacture.

Further objects and advantages will ap pear in the following description, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of a clothes pounder constructed in accordance with my invention; rig. 2 is a perspective view looking at the bottom of the clothes pounder; Fig. 3 is an enlarged detail sectional view showing the manner of coupling the handle receiving socket with the conical body portion.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved clothes pounder forming the subject matter of the present invention comprises a conical shaped body portion 5 preferably for sled of metal. and having its lower edge provided with a marginal rib 6 and its apex pierced by an opening, the interior walls of which are threaded at 7.

Detachably secured to the upper end of the body portion 5, is a socket 8 having its lower end threaded for engagement with the threads 7 and provided with a laterally extending shoulder 9, the lower face of which is curved upwardly for engagement with the laterally flared flange 10 of said body portion, thereby to form a tight fit be tween the parts and effectually prevent leaka 'e.

Evtending transversely across the body portion beneath the threaded walls 7, is a diaphragm or partition 11 having a valve seat 12 formed therein, which latter is normally closed by a spring pressed valve 13. The valve 13 is threaded on one end of a longitudinally disposed rod 14, the other end of which is projected longitudinally beyond the handle 15 to form a finger-piece 16. The handle 15 is fitted within the socket 8 and is provided with an interior bore or chamber 17 in which is seated a coil spring 18. The coil spring 18 encircles the rod 14 and is disposed with one end thereof secured to said rod, and its other end fastened to the adj a cent wall of the chamber 17 thereby to normally and yieldably support the valve 13 in closed position.

The socket 8 is provided with an air chamber 19 which communicates with an air chamber 20 of the conical shaped body portion 5, there being a piston 21 secured to the rod 14 and mounted for reciprocation in the chamber 19 so as to force a current of air through the valve seatwhen a longitudinal pressure is exerted on the finger piece 16.

Disposed within the conical shaped body portion 5 and secured in any suitable manner to the interior wall thereof, are a pluralit-y of tubular members or cells 22, the lower ends of some of which are disposed flush with the marginal rib, while the lower edges of others of said cells terminate approximately the center of the side walls of the body portion. The tubular members or cells 22 are connected with the air chambers 19 and 20 through the medium of conductors 23 so that when the finger-piece 16 is depressed, a portion of air in the chamber 19 will be forced downwardly through the cells I 22 and the clothes in the containing vessel, thereby to facilitate the washing operation.

A suitable vent opening 24 is formed in the socket 8 beneath the piston 21. for the purpose of admitting air to the chamber 19 when the valve is in closed position.

In operation, the clothes to be washed are spread over the top of the tub or other vessel containing the soap and water or other washing liquid, after which the pounder is positioned over the clothes and the piston 21 forced downwardly within the chamber 19 by exerting a longitudinal, pressure on the finger piece 16. On the downward movement of the piston 21, the valve 13 will be moved to open position thus allowing the air in the chamber 19 to be forced downwardly at the center of the body portion 5, a portion of the air in said chamber being forced through the conductors 23 and cells to the clothes to be washed, and on the upward movement of the piston, the air together with a portion of the water in the containing vessel, will be drawn upwardly through the cells 22 and valve seat 12 to the chamber 19, the liquid in the chamber 19 be ing returned to the clothes containing vessel when the handle 15 is again depressed, this operation being continued until the washing operation is completed.

Having thus described the invention, what is claimed as new is:

1. A clothes pounder including a cone shaped body portion having a plurality of cells of different heights secured to the in terior wall thereof,a handle receiving socket having an air chamber, and a piston mounted for reciprocation in said chamber for forcing a current of air through the cells.

2-. A clothes pounder including a cone shaped body portion having a plurality of cells secured to the interior wall thereof, a partition extending transversely across the apex of the cone shaped body portion and provided with a valve seat, a handle receiving socket detachably secured to said body portion and provided with an air chamber, a rod having a piston secured thereto and operating within the air chamber for forcing a currentof air through the cells, and a valve carried by the rod for normally closing the valve seat.

3. A. clothes pounder including a cone shaped body portion having an opening formed in the apex thereof, the interior walls of which are threaded, a handle receiving socket having corresponding threads for engagement with the threaded walls of the body portion, said socket being provided with an air chamber, a handle seated in the socket and provided with a longitudinally disposed bore, a rod extending through the socket and handle and having one end thereof projected longitudinally beyond the said handle to form a finger-piece, a coil spring seated in the bore of the handle and secured to said handle and rod respecth'ply, and a piston operating *ithin the cl'iamber of the socket for forcing a current of air within the conical body portion when the finger piece is depressed, there being a vent opening formed in the socket beneath the piston.

4-. A clothes pounder including a cone shaped body portion. hav 1g a threaded opening formed in the apex thereof, the walls of said body portion at said threaded opening bein flared laterally, a handle receiving socket threaded in the opening in the body portion and provided with an annular shoulder adapted to bear against the flared portion at the apex of the body portion, said socket being provided with an air chamber, a handle seated in the socket, a rod extending through the socket and handle and having one end thereof teuninating in a finger-piece, a spring operatively connected with the handle and rod respectively, and a piston operating within the chamber of the socket for forcing a current of air through the body portion when the fingerpiece is depressed.

5. A clothes pounder including a cone shaped body portion having a threaded opening formed in the apex thereof, a transverse partition eXtending across the upper end of the body portion to form an air chamber, a plurality of cells of different lengths secured to the interior walls of the body portion, conductors forming a source of communication between the cells and the air chamber, there being a valve seat formed in the partition, a spring-pressed valve normally closing the valve seat, and means for opening the valve and simultaneously forcing a current of air through the valve seat and conductors to the interior of the cone shaped body portion.

In testimony whereof I affix my signature in presence of two witnesses.
